摘　　要：太原武宿国际机场T3航站楼项目所在地抗震设防烈度高、地质条件复杂。T3航站楼主楼采用下部混凝土结构、屋盖大跨度钢结构的混合形式,并存在局部转换、扭转不规则、穿层柱、钢屋盖跨越下部混凝土结构单体形成连体等超限情况。对T3航站楼主楼的基础设计和下部混凝土结构消能减震设计进行了介绍,包括局部液化场地的地基处理、带板结夹层土层条件下锤击桩的设计、考虑承台作用的桩基水平承载力测试、减震与隔振方案的比选与确定等,并探讨了T3航站楼功能约束条件下的黏滞阻尼器不均匀布置对减隔震效果的影响情况,可为类似工程的设计提供参考。Taiyuan Wusu International Airport Terminal 3 project is located at a site with high seismic fortification intensity and complex geological conditions.The main building of Terminal 3 adopts a hybrid structure consisting of a lower concrete structure and a large-span steel structure for the roof.There are exceeding code limitation situations such as local conversion,irregular torsion,column penetration,and steel roof crossing over the lower concrete structure monomer to form a conjoined body.The foundation design and the energy dissipation and seismic reduction design of the lower concrete structure of the main building of Terminal 3 were introduced,including the foundation treatment of local liquefaction sites,the response of penetration of pile with hammer blow to the soil layer with hard laminated interlayer,the horizontal bearing capacity test of pile foundation considering the effect of the pile cap,and the selection of seismic reduction and isolation schemes.The influence of uneven arrangement of viscous dampers under the functional constraints of the Terminal 3 on the seismic reduction effect was discussed,which can provide reference for the design of similar projects.
